I have been trying to do mine on Balmung, Naul dies as soon as he is announced and the second we get there he is lagging in and out because of so many and by the time anyone gets there he is dead!

They really do need to make a few changes to the NM's like less spawn time for the lower ranks, I have seen the A rank one in the highlands then Naul. They also need more HP if a small group can down it in a few seconds it need more HP if more then 50 people are gonna be hunting this thing at one time.
